The headlights of a car are 1.6 m apart and produce light of wavelength 575 nm in vacuum. The pupil of the eye of the observer h
Xelga [282]

To solve this problem it is necessary to apply the concepts related to angular resolution, for which it is necessary that the angle is

\theta = 1.22\frac{\lambda}{nd}

Where

d = Diameter of the eye

n = Index of refraction

D = Distance between head lights

\lambda= Wavelength

Replacing with our values we have that

\theta = 1.22 \frac{(1.22)(575*10{-9})}{1.4(4*10^{-3})}

\theta = 1.252*10^{-4}rad

Using the proportion of the arc length we have to

L = \frac{D}{\theta}

Where L is the maximum distance, therefore

L = \frac{1.6}{1.252*10^{-4}}

L = 12.77km

Therefore the maximum distance from the observer that the two headlights can be distinguished is 12.77km

A possible explanation for a set of facts that can be tested by further investigation is called a blank
nadezda [96]

Answer;

Hypothesis

Explanation;

A hypothesis  is a tentative explanation that accounts for a set of facts and can be tested by further investigation. Scientific hypotheses must be posed in a form that allows them to be tested.

- It represents a possible explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation. Once you do the experiment and find out if it supports the hypothesis, it becomes part of scientific theory. An example of a hypothesis; Hypothesis: Bacterial growth may be affected by temperature.
